This is a web-based editor for file formats used by modern EFIS avionics systems on aircraft.

Preview

You can try it out directly in the link above, but here's what it currently looks like:

Supported file types:

• Checklists:
  • Advanced Flight systems (AFS)
  • Dynon Skyview
  • Foreflight (.fmd file format) - thanks to zyv!
  • Garmin G3X / G3X Touch / GTN (.ace file format)
  • Grand Rapids (GRT)
  • Printable (PDF) - export only

Internally, files are stored in our own format, so it is possible to import a file in one format and then export it in another.

File storage

For now, this is a standalone web app that doesn't talk to any servers. To accomplish this, files are stored on your browser's local storage. This does mean that if you lose your device or clear your browser's data, they will be lost - so download your files and keep a copy safe.

Disclaimer

Important

This is not your usual disclaimer - read it carefully.

Caution

☠️ Failure to follow proper procedures can result in serious injury or death. ☠️

Use of files generated by this application on your avionics is at your own risk, and we make no guarantee that the output will be correct or safe to use. Approach using these files with the same care that you would any flight testing activity - we recommend thoroughly testing them before use during actual operations (including checking them with the manufacturer's recommended apps where available, thoroughly testing on the ground before flight, having paper copies of your checklists, and any other precautions you would take when using an avionics configuration that's not supported or documented by your avionics manufacturer). We take no responsibility if it makes your EFIS crash, melt and/or you crash and die while attempting to use these files. We obviously also take no responsibility for the actual contents of your checklists, or even guarantee that the contents you enter in this app will be accurately reflected in your EFIS. Likewise, we make no guarantee that generated printable files will be correct, complete or safe to use as paper backups.

Experimental aircraft use only - use for certificated aircraft is not authorized.

The authors of this app have no association or relationship with the manufacturers of the avionics with which these files may be used, and its use is not supported by or endorsed by any of those companies.

Contributing

We welcome outside contributions, and there's plenty of things to do, so don't be shy. Please ask if you want a pointer on something you can help with, and hopefully we can all figure something out.

We do have a few policies and suggestions for contributors. The broad TL;DR:

• Bug reports are very welcome!
• Every commit that lands in the main branch is code reviewed.
• Please behave yourself, and obey the Community Guidelines.
• There is a mandatory CLA you must agree to. Importantly, it does not transfer copyright ownership to Google or anyone else; it simply gives us the right to safely redistribute and use your changes.

Contributions wanted

This is a short list of known areas where contributions would be helpful:

• UI refinement: As a backend developer (heck, nowadays I'm not even that, just a manager), my CSS-foo is quite limited. If you see something that looks odd, please send a PR!
• Format testing: I have not tested these files on anything but Garmin avionics and ForeFlight. Please test and send improvements.
• GRT live data: GRT supports showing live data on the checklist, which is pretty cool. Building that into the app (both to easily select a field to insert, and to render it with some fake data) would be nice.
• Moving items between checklists
• Reordering/moving checklists or groups
• Configuration files: I'd like to support more than just checklists.
• Your favorite missing feature goes here.

Development setup

The following steps can be followed to set up a development environment:

• If you haven't already, install Node
• Clone this project (we recommend using jj for that!)
• npm install (will install all dependencies into node_modules/)
• npm run genproto (will generate protocol buffer files into gen/ts/)

You can then develop as you normally would any Angular app (e.g. ng serve).

If you make changes to .proto files, you'll need to run the genproto step again (or you can use an IDE extension such as vscode-proto3 to do that automatically when the file is saved).
